The former Wimbledon champion Boris Becker has attempted to defuse his spat with Judy Murray but reiterated his view that she should reconsider her role as part of her son's entourage. After Becker said earlier this year that Andy Murray should cut his ties with his mother on tour, she dismissed the criticism as "nonsense", saying it was "a comment from somebody who knows nothing about our family life". But the three-times Wimbledon champion turned BBC commentator stood by his view that she should spend less time on tour with him.

"I just question whether a young man needs to have his mother around all the time in his job. I may be wrong but I don't see the mother of Nadal or Federer or Djokovic," he said today. "They come to the final or the semi-final but I don't think they have a real involvement in their games. At the end of the day, it doesn't matter what I think. The important thing is that it works for Andy."

Becker, speaking at the launch of a public serving challenge sponsored by Ralph Lauren to celebrate the 125th anniversary of the Championships, said it was impossible to separate the top four seeds ahead of the tournament. "All four have pretty much the same chance to go all the way," said Becker, who won his first Wimbledon title at 17. " "I want to see how they play but at the moment I would rate them all equal."
